How rare is hemophilia?

One out of 8,000 newborn baby boys is born with hemophilia. So about one in 8,000 male
births will be a boy with hemophilia. Females also have hemophilia although
it is far less frequent than in males.

How many people have hemophilia in the United States? About 17,000. That may seem like a
lot of you. But out of a total population of over 250 million, this
number represents much, much less than 1% of the population. You are
more likely to meet a person with Down syndrome, epilepsy, diabetes
or cystic fibrosis than someone with hemophilia.
